Let me explain clearly ,

Consider there is select field city in the form.
Now city dropwdown data should load from external rest api call /city.

When use come on form , on click on select drop down it should make ajax call and load the data in select dropdown.

cur_frm.set_df_property("my_select_field_name", "options", ["", "Hi", "Hey"])

i think it can also be done also using frappe.model.set_value by providing the array directly
